Board in DFU mode, no corrosion.
After unsuccessful restore show error 4014.
"4014 - Unexpected reset. Might be caused by T2 RAM error, power rail failure or even a bad battery.
History: Client left MacBook for long period of time so battery voltage was too low to be charged.
Battery replaced and after a few days came back.
Board was in DFU.
Tried of course with another battery and board only as well.
PPBUS_AON 12.27V
PP3V3_AON 3.28V
PP1V8_AON 1.8V
0.8V, 1.25V and 2.5V AWAKE_NAND rails have correct voltage.
Any idea?
